Head of Private Office, - AI Security Institute

Description

The AI Security Institute (AISI) is the largest team in a government dedicated to understanding AI capabilities and risks in the world.

Our mission is to equip governments with an empirical understanding of the safety of advanced AI systems. We conduct research to understand the capabilities and impacts of advanced AI, and develop and test risk mitigations. We focus on risks with security implications, including the potential of AI to assist with the development of chemical and biological weapons, how it can be used to carry out cyber-attacks, enable crimes such as fraud, and the possibility of loss of control.

The risks from AI are not sci-fi, they are urgent. By combining the agility of a tech start-up with the expertise and mission-driven focus of government, we’re building a unique and innovative organisation to prevent AI’s harms from impeding its potential.

This is an exciting opportunity to lead Private Office at the AI Security Institute , one of the UK government's most high-profile and fastest-growing teams, at the centre of how the UK and the world responds to the risks of frontier AI.

Private Office is the engine room that keeps AISI's senior leadership running effectively. As Head of Private Office, you will lead the team of Private Secretaries supporting the Director, Strategy Director and Deputy Directors, and be personally accountable for the overall quality, consistency and impact of that support.

This is a role with real scope to shape how AISI's leadership operates. Beyond running an excellent function, you will have the opportunity to become a trusted strategic adviser to the Director and senior team , helping shape how priorities are set, how decisions get made, and how the organisation runs as it continues to scale at pace.

The role has four core strands:

  • Driving excellence in Private Office , ensuring the function delivers consistently high-quality, resilient support across AISI's leadership team
  • Building out the function , introducing tools (including AI), processes and ways of working that make Private Office more effective and scalable
  • Developing the team , leading onboarding and development of Private Secretaries, and keeping resourcing and structure under review as the function's needs evolve
  • Being a strategic sounding board , contributing your own judgement and advice to the Director and senior team on priorities, decisions and how the organisation runs, drawing on your unique vantage point across the top of AISI

Key responsibilities

Leading the function:

  • Own the overall quality and consistency of support provided by Private Office, setting clear standards and ensuring they are met
  • Manage and develop the team of Private Secretaries, including coaching, feedback and cover planning, and building a culture that takes pride in operational excellence
  • Act as the point of escalation for complex, sensitive or cross-cutting issues that individual Private Secretaries can't resolve alone

Continuous improvement and tools:

  • Identify and implement opportunities to improve how Private Office operates, from streamlining processes to introducing AI tools and other technology
  • Build scalable systems, ways of working and resourcing that will serve AISI as it continues to grow

Developing the team:

  • Own onboarding for new Private Office joiners, ensuring they're set up to succeed quickly
  • Support the ongoing development of Private Secretaries, helping them build the skills and judgement to grow within their roles

Strategic sounding board:

  • Use your vantage point across AISI's leadership to spot patterns, risks and opportunities that individual Private Secretaries may not see from within a single portfolio, and ensure leadership's collective priorities , not just individual asks , are tracked and delivered
  • Act as a trusted sounding board to the Director and senior team , contributing your own judgement and advice on priorities, sensitive issues, and how the leadership group functions as a whole
